Debian DSA-3934-1 : git - security update

Medium Nessus Plugin ID 102374

Synopsis

The remote Debian host is missing a security-related update.

Description

Joern Schneeweisz discovered that git, a distributed revision control system, did not correctly handle maliciously constructed ssh:// URLs.
This allowed an attacker to run an arbitrary shell command, for instance via git submodules.

Solution

Upgrade the git packages.

For the oldstable distribution (jessie), this problem has been fixed in version 1:2.1.4-2.1+deb8u4.

For the stable distribution (stretch), this problem has been fixed in version 1:2.11.0-3+deb9u1.
